To all ywhom it may concern:

Be it known that l, HENRY Bannion, a citizen of the United States,residing Huntsville, in the county of Yvllallier and State of Texas,have invented certain new y and usefnl improvements in Envelop-Seals, ofwhich the following is a specification.

This invention relates to the class of receptacles, and moreparticularly to envelope, and has for an object to provide an envelopwith a simple seal by means of which the usual flap of an envelop may besecurely engaged with the body portion of the envelop and thus reventopening or tampering with same.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specilicstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

ln the drawings forming a 'portion of this 4 specification, and in whichlike characters of reference indicate similar pai-ts in the severalviews, Figure 1 is a rear view of an envelop slimving the application ofthe present invention thereto, Fig. 2 is vertical sectional view on theline 2-2 of F 1, Fig. .3 is a plan view from the interior of the en-lvelop showing the flap in its closed position, Fig. 4 is a perspectiveview of the locking I tongue, Fig. 5 is a perspective view of the tonguereceiving member, Fig. 6 is a perspective view of a slightly modifiedform of my invention.

Referring' now more particularly to the' drawings, there is shown anenvelop A of usual construction provided with a flap B, as shown. Theflap B is provided with the usual gummed surface C. rlhe rear wall l) ofthe envelop upon its inner side is provided with a metallic member 10substantially wedge shaped, and this member is provided with oppositelyextending lateral arms 11 and 12 respectively which are secured to theportion D of the envelop by means of rivets or suitable fasteningdevices 18 provided outwardly of the portion B of the envelop withwashers 14. The member 10 above the arms 11 and 12 respectively isprovided with an inwardly extending tongue 15 at each side, for apurpose to be hereinafter described, and beneath the arms 12 and 11 reispectively the member l() at each side is provided with a similar tongue16. The tongues 15 and 16 respectively are thus arranged in spacedrelation to the body portion of the member extending inwardly thereoveras shown in Fig. 5 of the drawings. The flap B is provided with ametallic member 17 having tapered side walls 18, and at the lowerl endthis member is provided with an arcuate head 19 barbed at each side, asshown at 20. The member 17 is secured to the flap B by means of a rivet21 similar to the rivets previously described, and this member isarranged with a portion extending below the 'flap B, as shown. lt willthus be seen that the gummed portion C of the flap B may be moistened inthe usual manner, alter which, the lap may be engaged with the portion Dof the envelop, and upon the outer side thereof. ln fastening the ilap Bto the portion l) of the envelop, the member 17 is disposed within theenvelop, and the head 19 is inserted between the tongues 15, and isfinali Y moved in a downward direction and bet 'een the tongues 16.After the head 19 has passed the lower edges of the tongues 16, it isobvious that the barbed portions 20 of the head will securely engage thetongues 16 and effectively prevent withdrawal of the member 17. it willthus be seen that a simple device is pro rided which may be stamped fromsheet material, and which will eifectivel* serve to prevent tamperingwith the envelop without detection.

While the device is especially adapted for envelops, it will of coursebe understood that the same may be used in connection with candy boxesor similar' pasteboard receptacles.

ln the modified form of my invention shown in `Fig. 6, the lockingtongue is provided at its center with a relatively broad portion 22, andat each side thereof the tongue is provided with tapered or reducedportions 24 and respectively. The barbed portions of the member 17 areoffset in opposite directions, as shown, to effect a perfect lockingengagement with the tongues 16 previously described.

As shown in Fig. 5, the member 10 and the portions carried thereby reformed of a sheet metal plate, the sides thereof being split inwardly toform the tongues 15 and 16, the latter being bent inwardly over the iaoeof the portion l0. The arms ll and 12 are formed by the portions of theplate between the s lits.

VVh-at is o aimed is:

The combination with an envelop having a closing lap, of a wedge-shapedplate located within the envelop with its major end directed upwardly,pairs of tongues Carried by the edges oi the plate at the upper andlower portions thereof, said tongues being bent to extend inwardly overthe inner face of the plate and in spaced relation thereto, said pair oftongues being spaced apart vertically;Y oppositely extending lateralarms carried by tne plate between the tongues,

said arms being secured to the envelop, and a downwardly taperedmetallic member oarried by the closing flap of the envelop, and havinglaterally extending barbs at its lower end, said member being arrangedfor passage l between the wedge-shaped plate and the tongues forengagement of its barbs beneath the lower tongues.

ln testimony whereof l affix iny signature, in presence of twowitnesses.
